I'm fixing an old bike I got out of a dumpster. The tubes needed replacing and the tires had cracks all over the surface (picture 3). Since tires are held together by a weave and not just rubber I imagined it would still be somewhat safe to ride. About an hour after inflating it to 4.5bar (the ma...

I'm totally new to piano. I have a background in guitar, programming and some math, therefore I tend to think a little in an "exact number of boxes" fashion or "an array of numbers" as in programming. From the little I've learnt so far, I've become used to finding a complete subdivision of the ti...

I know light bulbs resistance varies depending on heat. What about heating elements? Would 2000W heating element have 26.45 Ohm (230V / 26.45 Ohm = 8.7A, so 8.7A * 230V = 2000W) resistance both in room temperatures and at 100 C degrees?

just like the question says - My battery drains fast on my iphone-13 - is there a way to determine which app(s) have been using the most CPU in the last month? (In other words, I don't want a snapshot from just the last 10 seconds or whatever, but rather in total over the last month).

Since my beginnings with Advanced Dungeons & Dragons until now (playing Wrath of the Righteous, having played 2e and Pathfinder in between), I'm still asking myself: Is there, in term of D&D game mechanics, an interest of equipping a normal show bow rather than a normal long bow? Immediately, the...

Today I went nearly crazy while working on an Aura component. I'm saving my work but the UI does not update. Damn! Waiting a while (about 10 minutes) my changes are finally showing up.

I'm designing a moderately powerful motor controller (integrated into a product). The board runs on 24V and has a 100uF electrolytic input cap, as well as 2 10uF ceramics near the switcher. Whenever I connect this board to power, there is a hearty spark. It hasn't noticeably damaged anything yet,...

It seems unlikely that Starfleet officers would be allowed to "take a break" during times of war, such as during the Dominion War. However, Starfleet isn't 100% a military organization, so I could be wrong. Are there any known scenarios of Starfleet officers going on leave during war?

I have a module, pod. I am attempting to alter another service (group.relation_handler.access_control.group_content_menu), by implementing Drupal\pod\PodServiceProvider::alter().

Do larger rockets tend to have a better mass ratio due to the square cube law? I mean, larger tanks have a better surface-to-volume ratio, so their weight-to-volume should be improved

Anything that has avocados in the recipe is ten times better in my opinion, in tacos, in salad, on toast, on soup, etc... but it's a tricky fruit. Often the grocery store only has tough, green avocados that aren't ready to be cut and eaten, but you need them that night for your dinner recipe. How...

I read a paperback in the early 80s, can't remember the title. Aliens were going to attack Earth but Earth was warned as scouts attacked early around Colorado and we figured them out. The planet got together and built a huge grazer (LASER except for Gamma rays, not light) to destroy the incoming ...

A lot of the time when working in DevOps, documentation and code snippets from colleagues will be based on bash. Most of those same commands work seamlessly in PowerShell; but setting environment variables doesn't; e.g. export DEMO_CLIENT_ID="ff3b7b84-e041-4e76-993e-239930808aa7". I've written t...

I am building a monte carlo based on the GMB, and I am having a hard time understanding why we subtract 1/2 variance from the drift. If I have a drift of 12% and a volatility of 50%, that would give me "mean" drift of -.24% based on this. That doesn't make sense to me. If I am expecting the asset...

This is the lightbulb above my shower. I have removed an outer fixture covering already, but now I am faced with a light bulb that cannot be unscrewed easily. It is mounted to the ceiling in a plastic fixture I have not seen before. What is the appropriate way to replace this bulb? Am I able to r...

I am beginning to learn some very basic electronics. I was learning how and why lightbulbs light up. It turns out it happens because they have a very thin filament which makes the passage very narrow for electrons so they lose a lot of energy colliding with the molecules making up the filament in...

What's the antonym for educated guess? Is it 'uninformed guess' or just 'guess'? Is there such thing as 'uneducated guess'? I couldn't use it as it only negates part of a phrase and doesn't seem opposite of 'informed/educated guess'.

I don't understand where is the flaw in my logic, or where my mistake lies.

Over the weekend, the Bitcoin mempool size exceeded the default 300mb limit and was purging transactions.

Does the second law of thermodynamics apply to a single electron in deep space? Or two electrons? Or 100? (assume the electrons are restricted in a finite area) From which point we can start to talk about the entropy of a closed system?

In the old PC mags, there were often printouts of code from Commodore PETs. How were these done? Even though the PET had a GPIB interface, it didn't have a print command. The method that we used in 1978 was a little machine code program to show one line at a time on the top of the screen and th...

I was reading certain datasheets for GaN MOSFETs and came across manufacturers saying about achieving "Ultra Low Inductance".

I have an interior wall outlet around the location on the picture... lower on the wall. I need an outlet for the water heater. Would you suggest I drill directly through the brick where the outlet is or to put it higher? I also plan to power two water pipe heater wires so maybe having it closer t...

Backstory - I was accepted for a PhD at an excellent university in a new and exciting field I've been working towards for a long time. Due to a number of issues, I had to delay my start date for 6 months. One of those issues was the death of a parent I've been struggling to get over since it happ...

The left crankarm of an HollowTech II crank has a little part called "safety plate" (number 4 on the drawing below). What is exactly its role, and what kind of 'safety' does it offer given the forces applied on a crank, it's unlikely that it will make a difference if the bolts get loose)? Is it a...

I'm very new to Blender, so maybe there is a simple solution. I just learned the Rigid Body animation. My aim is to let a somewhat simple object (a carrot by wojtekgr from here) fall onto a plane. However, it always fells through the plane. Directly setting the carrot to a rigid body (with convex...

How to write a long $\rightharpoonup$ with the possibility to write something above and below the arrow. I need to write below $k \to +\infty$, so the $\rightharpoonup$ must be as long as $k \to +\infty$.

My friends and I disagreed playing the zombie attack of Haunt 21. The rules say that zombies are only killed by attacks from Might weapons. Any other attacks will only stun them. Some people say that since Speed and Might are both Physical attacks, a Speed attack counts as a Might attack and will...

My dad just told me that he had accepted a passive income job offer on Whatsapp where the task is to like the linked Insta post every 20 mins to earn money. The amount is too good for such job and my dad had really received the money and cashed some of it out. I can't help but think that this is ...

I am modeling a Nissan Z GT500 and I am wondering if it is possible to wrap a mesh on a curved object. I don't know how to explain so I try to show what I want to do with a picture: Basically I want to wrap my Z mesh like on the balloon on left picture, not cutting into it but to be on the surfa...

Here is a simple example to illustrate my problem: expr = {a + b*Exp[-r t], a - b*Exp[-r t]} (* {a + b E^(-r t), a - b E^(-r t)} *) g[t_, b_] := Total[Evaluate[expr], {2}] g[10, {b1, b2}] (* {a + b E^(-r t), a - b E^(-r t)} *) It looks is like Total[] undoes the Evaluate[] statement. Indeed: g...

In textbooks on many-body quantum physics (e.g. Fetter and Walecka), Feynman diagrams are typically introduced after formulating the Dyson perturbative expansion of the Green's function using Wicks theorem. Then the Feynman diagrams follow as a way to conveniently represent the resulting integral...

One of the common rulings my DM allows at my table is the usage of any source of music or wordplay to grant Bardic Inspiration, if you have that class feature. For example, I commonly use Minor Illusion to keep my hands free as a bard, seeing as it allows you to create music or discrete sounds ov...
